    CVE-2017-9445 Detail

    Deferred

    This CVE record is not being prioritized for NVD enrichment efforts due to resource or other concerns.

    Description

    In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.
